q2, are we asked to determine what was used to create the given HTML file, malicious.pdf, or are we supposed to find the MD5 hash of the PDF format? I’m not sure about this.
q3, I converted the images from base64 format and researched it, but I didn’t get any Gmail information from it.
q4, How can we get the MD5 format? Do we need to delete something from the given file and create a PDF? I don’t understand.
